Abstract

Provided is an array substrate, comprising a common electrode layer, an insulating layer, and a sensing layer which are sequentially stacked. The common electrode layer comprises multiple touch electrodes which are provided at intervals. The sensing layer comprises multiple touch lead wires and multiple suspension lead wires. The touch lead wires are provided above the touch electrodes, and are electrically connected to the touch electrodes by means of via holes. The suspension lead wires are provided above the intervals between every two touch electrodes, and are electrically connected to the touch lead wires by means of first lead wires. By electrically connecting suspension lead wires to touch lead wires, the electric potential at the suspension lead wires and the electric potential at touch electrodes are the same, thereby reducing the electric field difference between the regions between adjacent touch electrodes, and the touch electrodes, and avoiding the strip mura phenomenon occurred when light leaks from a liquid crystal layer due to the fact that the electric field formed by data lines located below the touch electrodes enters the liquid crystal layer above by means of the regions between the touch electrodes and drives the liquid crystal to flip.

请参阅图1～图3，本发明的阵列基板100包括：基板10、公共电极层(图未编号)、绝缘层30和感测层40，所述公共电极层形成于所述基板10的表面，所述绝缘层30涂覆于所述基板10的表面，且覆盖在所述公共电极层，所述感测层40形成于所述绝缘层30之背离基板10的表面。所述公共电极层包括多个触控电极21，所述多个触控电极21间隔设置。所述感测层40包括多条触控引线41和多条悬浮引线42。所述触控引线41正对所述触控电极21设置，换言之，触控引线41在基板10上的正投影大部分被触控电极21覆盖。所述触控引线41通过设置在绝缘层30上的过孔31与所述触控电极21电性连接。所述悬浮引线42设置在两个触控电极21之间的间隔上方，也就是说悬浮引线42在所述公共电极层上的投影位于两个触控电极31的间隔；第一引线43电性连接所述悬浮引线42和所述触控引线41。1 to 3, the array substrate 100 of the present invention includes a substrate 10, a common electrode layer (not numbered), an insulating layer 30, and a sensing layer 40. The common electrode layer is formed on the surface of the substrate 10. The insulating layer 30 is coated on the surface of the substrate 10 and covers the common electrode layer, and the sensing layer 40 is formed on a surface of the insulating layer 30 facing away from the substrate 10. The common electrode layer includes a plurality of touch electrodes 21, and the plurality of touch electrodes 21 are spaced apart. The sensing layer 40 includes a plurality of touch leads 41 and a plurality of floating leads 42. The touch lead 41 is disposed opposite to the touch electrode 21 . In other words, the orthographic projection of the touch lead 41 on the substrate 10 is mostly covered by the touch electrode 21 . The touch lead 41 is electrically connected to the touch electrode 21 through a via 31 disposed on the insulating layer 30 . The floating lead 42 is disposed above the interval between the two touch electrodes 21, that is, the projection of the floating lead 42 on the common electrode layer is located at intervals of the two touch electrodes 31; the first lead 43 is electrically The floating lead 42 and the touch lead 41 are connected.
本发明中，通过将悬浮引线与触控引线电性连接的方法，使得悬浮引线42处的电位与触控电极21的电位相同，从而减少了相邻触控电极之间区域与触控电极处的电场差异，避免了位于触控电极下方的数据线(Data line)形成 的电场会经触控电极之间区域窜入到上方的液晶层，形成水平方向的电场，驱动液晶翻转，从而导致造成该位置漏光，出现条状波纹(Mura)现象的发生。In the present invention, by electrically connecting the floating lead and the touch lead, the potential at the floating lead 42 is the same as the potential of the touch electrode 21, thereby reducing the area between the adjacent touch electrodes and the touch electrode. The electric field difference avoids the formation of the data line under the touch electrode The electric field will enter the upper liquid crystal layer through the area between the touch electrodes to form a horizontal electric field, which drives the liquid crystal to reverse, thereby causing light leakage at the position and occurrence of a strip-like ripple (Mura) phenomenon.
为验证本发明的技术效果，将悬浮引线连接至触控电极(sensor)和悬浮引线不连接至触控电极(sensor-f)两种情况在模拟软件中进行模拟，并得到暗态时的Pixel光学模拟结果如下表所示：In order to verify the technical effect of the present invention, the floating lead is connected to the touch electrode and the floating lead is not connected to the touch electrode (sensor-f), and the simulation is performed in the simulation software, and Pixel is obtained in the dark state. The optical simulation results are shown in the following table:
Figure PCTCN2016090608-appb-000001
Figure PCTCN2016090608-appb-000001
将上表中数据在坐标轴中标出，请结合参阅图4，图中横轴表示视角，纵轴表示光线亮度相对值。例如，当视角为60度时，悬浮引线连接至触控电极(sensor)时的亮度相对值为0.458；当悬浮引线不连接至触控电极(sensor-f)时的亮度相对值为0.612。也就是说悬浮引线连接至触控电极比悬浮引线不连接至触控电极的亮度下降了34％，从而能有效降低漏光。从图中也可以看出，无论哪种视角下，将悬浮引线不连接至触控电极时，Pixel暗态的亮度均比悬浮引线连接至触控电极时的亮度更高，即光学漏光的风险更高。通过本发明能够有效降低了显示时的光学漏光风险，有利于改善显示时的Mura不良。Mark the data in the above table in the coordinate axis. Please refer to Figure 4, where the horizontal axis represents the angle of view and the vertical axis represents the relative value of the light intensity. For example, when the viewing angle is 60 degrees, the relative value of the brightness when the floating lead is connected to the touch sensor is 0.458; the relative value of the brightness when the floating lead is not connected to the touch electrode (sensor-f) is 0.612. That is to say, the brightness of the floating lead connected to the touch electrode is 34% lower than that of the floating lead not connected to the touch electrode, so that light leakage can be effectively reduced. It can also be seen from the figure that, in any viewing angle, when the floating lead is not connected to the touch electrode, the brightness of the Pixel dark state is higher than the brightness when the floating lead is connected to the touch electrode, that is, the risk of optical light leakage. higher. According to the present invention, the risk of optical light leakage during display can be effectively reduced, and the Mura defect at the time of display can be improved.
